Allergen Awareness in Ireland: The 14 Allergens and the Law
For someone with a serious food allergy, the wrong meal can be life-threatening. Irish law is clear about what food businesses must tell their customers — here are the fourteen allergens and the duties that come with them.
Why allergens are treated so seriously
A food allergy is the immune system reacting to a normally harmless food. For some people the reaction is mild, but for others it can be sudden and severe, including anaphylaxis. Because the consequences can be so serious, allergen information is not optional courtesy — it is a legal duty designed to keep customers safe and informed.
In Ireland this is governed mainly by the EU Food Information for Consumers Regulation (1169/2011), overseen by the Food Safety Authority of Ireland (FSAI) and enforced by Environmental Health Officers (EHOs).
The fourteen named allergens
EU law names fourteen allergens that must be declared whenever they are used as an ingredient or processing aid. Every food business should know them by heart:
- Cereals containing gluten (wheat, rye, barley, oats and others)
- Crustaceans (such as prawns, crab and lobster)
- Eggs
- Fish
- Peanuts
- Soybeans
- Milk (including lactose)
- Nuts (such as almonds, hazelnuts, walnuts and cashews)
- Celery
- Mustard
- Sesame seeds
- Sulphur dioxide and sulphites (above defined levels)
- Lupin
- Molluscs (such as mussels and oysters)
If one of the fourteen is in the dish, the customer has a legal right to know — and a guess is never an acceptable answer.
What the law requires
Under EU FIC 1169/2011, allergen information must be provided for both prepacked and non-prepacked food, though the way it is given differs.
Prepacked food
Allergens must be listed in the ingredients list and emphasised — for example in bold — so they stand out clearly. The information must be accurate and legible.
Non-prepacked food
For food sold loose — in restaurants, cafés, takeaways and delis — allergen information must still be available to the customer. It can be provided in writing, such as on a menu or a folder, or signposted so a customer knows how to ask, but it must be accurate and easy to access.

Cross-contamination is the hidden risk
Declaring allergens correctly is only half the job. The other half is preventing one food's allergen from ending up in another by accident. A shared chopping board, a single fryer, or a utensil used across dishes can all transfer an allergen to a meal that should be free of it.
Good practice includes cleaning surfaces and equipment thoroughly between tasks, separating ingredients in storage, and being honest with customers when you genuinely cannot guarantee a dish is free of a particular allergen. Allergen control fits naturally within a wider food safety system, as explained in our guide to the seven HACCP principles.
Training your team
Every member of staff who serves food should be able to answer an allergen question correctly and know who to ask if they are unsure. The wider legal framework behind these duties is covered in our overview of food safety and the FSAI in Ireland.
Key takeaways
- Fourteen allergens must be declared by law under EU FIC 1169/2011.
- Information is required for both prepacked and non-prepacked food.
- On prepacked food, allergens must be emphasised in the ingredients list.
- For loose food, accurate allergen information must be readily available.
- Cross-contamination control and staff training are essential alongside labelling.
Handling an allergen request well
How staff respond when a customer mentions an allergy says a great deal about a food business. The right approach is to take every request seriously, to check rather than guess, and to be honest about uncertainty. A member of staff who says "let me check the ingredients for you" is far safer than one who assumes a dish is fine.
- Listen carefully and confirm exactly which allergen the customer is asking about.
- Check accurate, up-to-date allergen information rather than relying on memory.
- Be clear if a dish cannot be guaranteed free of an allergen due to shared equipment.
- Pass the request to a senior member of staff if there is any doubt.
Keeping allergen information accurate
Allergen information is only useful if it is correct. Recipes change, suppliers substitute ingredients, and a single swapped product can introduce a new allergen without anyone noticing. Reviewing allergen records whenever ingredients or suppliers change — and checking the labels on delivered stock — keeps your information trustworthy. Inaccurate allergen information is arguably worse than none at all, because it gives a vulnerable customer false confidence.
The bottom line
Allergen management protects your most vulnerable customers and your business at the same time. Learn the fourteen, give accurate information every time, control cross-contamination, and make sure every member of your team can do the same. That is the standard Irish law expects — and the one your customers are trusting you to meet.
